i Application led October 28, 1922. Serial No. 597,467.

T 0 all uhomit may concern;

Be it known thatl I, JEROME BAnLow, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and

State of Illinois, have invented certain new and' useful Improvements in Heaters, of which the following is a specification.

This invention relates to heaters, and has for its object the provision of a heater, particularly adapted to be connected with a heating `plant of any suitable kind to serve as a substitute or auxiliary heat producing agency, together with means for directing -a current of air through the heater to facili- 1'5 tate distribution of the heated air throughout the `heating plant.

Another object of the inventionl is to arrange a plurality of electrical heating elements in spaced relation, and in substantial l0 parallelism withl a current of air under pressure directed therepast for effectively heating such air together with means for spreading and distributing the air over the heating elements. f

Other objects willi' appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will /be best understood by reference to the accompanying drawings forming a part of this specification, and in` which, t

Fig. 1 is a vertical section of uthe invention, showing parts thereof in full lines; Fig. 2 is a sectional view of the invention, on the line 2.- 2 of Fig. l; y f jFig. 3 is a sectional view of the invention on the line 3-3 of Fig. 1; and

Fig. 4 is a sectional view of the invention on the line Lt-4 of Fig. 1. A I The heater contemplated herein is primarily intended as a substitute or auxiliary device intended to be interposed in, or coni nected with, heat distributing systems ofl various types of heating plants, and may be connected with the casing ofafurnace, with a single flue, if desired, or other suitable portion of the heating plant.

Referring to the drawings, 10 represents '50 fragment of a furnace casing, though it is obvious that any other suitable portion of the heat distributing system may be utilized,

as above explained: and 11 represents asuitable connection which communicates with the interior of -la heater 12.Y The heater 12 preferably comprises a hood 13 having a chamber 1l, such hood being preferably detacliably mounted upon a somewhat larger body portion 15 having a chamber 16 therein', such body portion being mounted upon a suitable pedestal 17. The provided with a base 18 having a flange 19, adapted to support a housing 20, preferably of asbestos. which incloses the heater 12s Mounted in the upper portion of the chamber 16 is a frame 21, which is preferably inthe form of a cross. Such frame i pedestal 1T is may be provided with suitable apertures 22 adapted to accommodate elongated heating elements 23, such heating elements each being provided with a ange 21, adapted to rest upon the frame 21 so as to suspend the heating elements inthe chamber 16 `Vas shown. The heating elements 23 eachcomprises a body of insulating material having coils 25 of resistant wire thereon, said elements preferably being connected in parallel by the wires 26 and 2T, such wires extending outwardly through the housing 20 and being connected with a. lsuitable source of current (not shown).

The pedestal 1T is provided with an inverted conical chamber 28, at the mouth of which is mounted a plate 29 having a plurality of spaced perforations 30 therein. The inner end of the chamber 28 communicates with a bore 31, in the pedestal 1T,y and with a conduit 32, which may be connected to a compressed air tank 33 provided with a suitable pump 3l and motor 35 for driving the same. If desired, instead of the compressedairfoutfit, an ordinary blower fan (not shown) might be used. `The bore 31 may be provided with any suitable valve for regulating the passage of air through the conduit 32 and the vheater 12. a valve36 is slidably mounted in the bore 31, such valve preferably having a stem 3T upon which is provided a rack 38 engaged by a pinion 39 mounted upon a shaft 'i0 extending to the outside of the housing 20.

By this arrangement a current of air vunder pressure is directed through the heater,

As shown,

such current of air being controlled by the fore passing into the heat distributing s 's- 'Y tem of the heatingplant.

'hile l have illustrated and described the preferred form of construction for carrying llt) my invention into. eliect, this is capable of variation and modification Without departing from the spirit of the invention. I, therefore, do not Wish to be limited to the precise details of construction set forth, but

desire to avail myself of such variations and -said heating means including a frame `With separate elongated heating elements extending therefrom parallel to the direction of flow of said fcurrent of air.

2. The combination, with the heat distributing system of a heating plant; of an auxiliary heating device connected with said system, and including a supporting pedestal with an air passage; means for directing a current of air under pressure through `said passage and auxiliary heating device and into said heating system; and

' means in said pedestal for regulating the How of air through said passage and heating system.

3. The combination, with the heat distributing system of a heating plant: of an auxiliary heating device connected with said heat distributing system, and including a body portion ivith heating elements therein; a supporting member for said body portion; means for directing air under pressure through said supporting member and body portion and into said heat distributing system; and means in said supporting member for regulating the passage of air through sa/id auxiliary heating device and into said heat distributing system.

4. The combination with the heat distributing system of a heating plant; of an auxiliary heating device connected with said heat distributing system, said heating device having a passage therethrough communicating with said system; electric heat-` ing elements mounted in said passage;

means for directing compressed air throughy 5. TheY combination, with. the heat dis.-

tributing system of a heating plant; of a housing disposed exteriorly of said heat dis-v tributing system, and containing an auxillary heating device .connected with said system, said heating device including a body -portion having a passage therethrough communicating with said system; a -frame- ,mounted in said body portion and having electric heating elements mounted thereon and extending parallel with the flow of air vthrough said passage;A means for directing compressed air through said passage and into said vlieat distributing system; and

means for regulating the flow of air through said passage.-

6. The combinationV with the heat distributing system of a heating plant; of an i auxiliary heating device connected with said heat distributing system, said heating device having a passage therethrough communicating with said systems; electric heatmg elements mounted in said passage ;'means for directing compressed air through said passage and into said heat distributing l system; means for distributing said air over said heating elements; and means for regulating the flow of air through said passage.-

7`. The combination Awith the heat dis-A tributing system of a heating plant, of an auxiliary heating device disposed exteriorly of said heating system; said'heating deviceincluding a. body portion; a frame mounted in said body portion having means for supporting a plurality of electric heating elements; a pedestal for supporting said body portion, said pedestal having achamber therein/communicating' with said body portion; means forl directing air under pressure throughsaid body portion; and a valve mounted in said pedestal for controlling the passage of air through said body portion and into said heat distributing system.

In testimonyjvirhereof I have signed my name to this specification .in the presence of two subscribing witnesses. i
